BepiColombo is European Space Agency’s (ESA) mission to Mercury. The BepiColombo spacecraft will be launched in October 2018 towards the planet Mercury where it will arrive in approximately six years. One of the payloads is the SIXS instrument (Solar Intensity X-ray and particle Spectrometer) developed in a Finnish consortium lead by the Division of Geophysics and Astronomy of the University of Helsinki. The Sensor Unit of SIXS consists of two main parts: an X-ray detector system and a proton and electron detector system. Oxford Instruments is responsible for the design, development, manufacturing, and testing of the X-ray detector system and the Sensor Unit for the SIXS instrument. The design and testing of the particle detector was conducted by ASRO, Finland.

Thermal analysis and design of the SIXS instrument was performed at Ideal Engineering Oy by Matti TalviOja, current CEO of Talvioja Consulting Oy.


CubeSat designs

Resent work very much concentrated in thermal management of CubeSat designs. Example for instance RSL’s (Reactor Space Lab) “Hello World” –nanosatellite.


MEDA HS sensor

Over the years Matti TalviOja has been a contributor to nearly all FMI’s (Finnish Meteorological Institute) Mars exploration projects as a thermal design specialist. The latest is MEDA HS sensor onboard US Mars 2020 Rover.
